STEREOTYPERS CASTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 457,896, dated August18, 1891. Application filed December 31, 1889. Serial No. 335,542. (Nomodel.)

To all whom it may concern.-

Be it known that 1, JOHN RAYMOND CUM- MINGS, of Chicago, Cook county,Illinois, have invented certain new and useful Improvements inStereotypers Casting Apparatus, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The object of my invention is to facilitate the pouring of the moltenstereotype metal into the mold so as to enable one man to do the work oftwo men, and so as to greatly facilitate the work of casting,substantially as hereinafter fully described, and as illustrated in thedrawings, in which I Figure 1 is a side elevation of my invention. Fig.2 is a plan view thereof.

Referring to the drawings, A represents a furnace with a molten-lead potin its top, and B represents a stereotype-casting appa ratus which isplaced alongside of said furnace a suitable distance away. I

The stereotype apparatus consists of a box and cover, (corresponding tothe cope and drag, respectively, of an ordinary m0ld,) which areoscillated from a horizontal to a vertical position after the matrix isplaced therein preparatory to casting. In order for one man to raisesaid casting from the horizontal to the vertical position without theexpenditure of much time and strength I counterbalance the same by meansof the ropes a, which I attach to the box of the same, and from thencepass up over the pulleys b1), and have their free ends provided with asufficient weight a.

C represents a large ladle, which is of such capacity as to holdsufficient metal to make one casting. This ladle is provided with ahandle by which the operator controls it, and is also provided with abail d, to which is attached a rope e, which passes up through asuitable pulley f, and is provided at its free end, which hangs down towithin easy reach of the operator, where it is weighted, with a suitablehand-grasp g. The rope c, after it leaves the hail of the ladle, passesup through a suitable opening in the revoluble guidearm D, which is on aplane sufiiciently above the top of the furnace to permit of the ladlepassing over the furnace, and which is of such a length and has itsvertical post so located that the path described by its end will moveover both the lead-pot of the furnace and the casting apparatus.

The operation of my invention is substantially as follows: The castingapparatus having been previously prepared and oscillated to a verticalposition, the guide-arm is turned so as to bring the ladle overthelead-pot of the furnace. The ladle is then dipped into the same andfilled and lifted out of the same by slightly pulling on the hand-graspsg of rope e untilthe bailof the ladle bystriking against the end of thecrane prevents further lifting thereof. The operator grasping the handleof the ladle with one hand pushes it toward the casting apparatus, theguide-arm through which its suspending-rope 6 passes guiding its courseinfallibly thereto, whereupon its contents are poured into the mold, andit is returned to or toward the furnace.

The perfect control which the operator has over the ladle by myimprovements, which before required two men, and was by them often ofnecessity handled awkwardly, greatly facilitates and materiallydecreases the expense of casting stereotypes.

What I claim is The combination, with a stereotypers furnace, a bracketprojecting therefrom having a post arising from it, and a revolubleguidearm pivoted at one end to said post and of such length that it canbe moved over the pot in the top of said furnace, of a ladle C, a ropesuspending the same, and pulleys f f, said rope after it leaves saidladle passing up through a suitable opening in the end of saidguide-arm, from thence independently of said arm to a point above andabout in vertical alignment with-the pivotal center thereof, and afterpassingover said pulleys having its weighted end hanging down contiguousto said furnace, as set forth.
